Possible gunman suspect in Chicago bus shooting identified

An employee at the school attended by a 16-year-old who was shot and killed on a Chicago city bus has identified the possible gunman after looking at surveillance photographs.

No arrests had been made in the shooting that also injured four other teens two boys and two girls but police are looking for the suspect, who was also 16, said police spokeswoman Monique Bond.

Bond said authorities believe the shooting was gang related and that the gunman was aiming at someone else when he fatally shot 16-year-old Blair Holt. She said Holt was not a member of any gangs.

She declined to release the suspect's identity, but said he is not a student at the school and that the employee recognized him after looking at what she said was a "very clear picture" taken from the bus' surveillance camera.

A teenager boarded the Chicago Transit Authority bus Thursday afternoon, began shooting and then left, authorities said. He had killed Holt and injured four others three of whom were treated and released from hospital. The fourth was listed in fair condition by Friday.
